Open Crop Image to Square (1:1) OnlineWhere 1:1 is required
Social profile pictures, comment avatars, WhatsApp and gaming profiles, marketplace listings and Instagram grid posts. A square crop keeps the image intact without the auto-crop distortion social apps often apply.
Steps to a perfect square
- Open the [Crop Image tool](/tools/crop-image).
- Drop your photo.
- Select the 1:1 ratio preset — the frame becomes a locked square.
- Drag to center the subject.
- Download as JPG or PNG.
Keep a little headroom around the face — some platforms apply their own circular or tighter crop on top.
Finish the job
After cropping to 1:1, resize to the exact platform size with [Resize Image](/tools/resize-image) (1080×1080 for Instagram, 500×500 for WhatsApp) and compress to under 200KB with [Compress Image](/tools/compress-image).

Frequently Asked Questions
Why does the crop frame stay square automatically?
The 1:1 ratio preset locks the width-to-height at exactly 1:1 — you can reposition and resize, but the proportions never warp.
What size should a square profile photo be?
1080×1080 is the safest for social platforms; 500×500 is enough for WhatsApp. Crop to square first, then resize.
Will cropping to square lose the sides?
Yes — a square crop keeps the tallest possible center section. Center your subject before cropping to keep what matters.
